Good bye Let It Go, Hello Middle Earth & Rudy's
The start loop will remain the same, as will the main Big NIMBY climb. However, riders will not go up the final part of the Big NIMBY (called Let it Go), instead riders will turn right onto a short connector trail to the main FSR then go left and up the main FSR toward the paraglide launch past the entrance to Fifty, just before the launch riders will hang a right and climb Middle Earth. Riders will ascend Middle Earth until about the halfway point where they will hang a right and enter the amazing (somewhat) new descent, Rudy's - the Rudy Rozysypalek memorial trail. POV helmet cam video here. Rudy's ends where the Red Bull Downtime on Overnight Sensation begins.

Good bye Sphincter, Hello Lake Loop & Econoline forwards
After Overnight Sensation, here's the other big change: riders will follow the main FSR toward the Mosquito Lake area trails, however, instead of heading up to the oh-so-punchy Sphincter rock zone, the course will instead go left up a short climb to the top of Lake Loop. A fun, zippy descent with a small rise in the middle and a flat techy section to finish. Lake loop brings riders to the bottom of No Err where you'll follow the FSR up and complete a full loop of No Err, then instead of Smell the Glove, riders will climb Econoline (opposite direction than previous years) and then take the Econoline descent to mereg with the uber-fun (but challenging) descent Eono-Dave to finish off the course in the same manner as previous years.
